Weatherford McMurry-Macco™ Dummy Valves are retrievable, isolation tools installed in side pocket mandrels to prevent communication between the casing and tubing. These valves have two sets of packing which straddle and packoff the casing ports in the side pocket mandrel.

Dummy Valves with appropriate latches may be installed or retrieved prior to or after completion for various procedures.

In addition to sealing off the pocket of a side pocket mandrel, dummy valves are also used to blank off the tubing for production until gas lift valves are required. Other applications include pressurizing the tubing in various procedures, isolating tubing and casing flow during single-alternative production, and isolating tubing and casing flow for test purposes during mutli-point water or gas injection floods. Several models are available.

RD-1 Dummy Valve – 1-in. OD valve model

RD-2 Dummy Valve – 1.5-in. OD valve model
